06 Outback Wagon 2.5i charging
When ever it gets below twenty degrees overnight and I start the car up I get two lights on the dash. The battery light stays on for a long time even at 2500 RPM for a sustained period of time. Above 20 degrees it does not happen . Heated windshield OFF, heated Seats , OFF heated back lamp , OFF car heater fan OFF , heated Mirrors off car lights are on . Brand new Alternator (not reconditioned : NEW) , brand new battery , new belt on Alternator . Anyone have any idea why it does this ?
